Title: Improvements in or relating to matrix switches
Inventor: AYRES SIDNEY DENNIS
IPC: H01H67/26
Filed: 1966-03-08
Abstract: 1,137,533. Electric selectors. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 8 March, 1967 [8 March, 1966; 12 Jan., 1967], Nos. 10142/66 and 1789/67. Heading H1L. In a matrix switch having at each cross-point at least one fixed and one moving contact, the commoning between contacts of a row or a column is provided by conductive strips mounted upon an insulating surface, such as by moulding the strips into an insulating board or by printed circuit techniques, the commoning strips for a row of moving contacts being upon one insulating surface and those for a column of fixed contacts being upon another insulating surface. The two surfaces may be upon separate insulating boards or on opposite faces of the same board. In one arrangement (Fig. 1), where there are four pairs of contacts at each cross-point, the columns of fixed contacts 31 are mounted upon one side of boards 32 and make contact through the board with commoning strips upon the underside. The moving contacts are not shown, but are wires (Figs. 3 and 4, not shown) mounted upon the cross-members 36, into which boards 32 are slotted, and at one end are bent to overly the respective fixed contact and at the other end pass through the cross-member to connect with row commoning strips 42 mounted upon the upper side as shown, or alternatively the lower side of the boards 43. The four moving contacts at a cross-point are mechanically bridged so that they may be operated together, such as by a fluid or electromagneticallyoperated cross-bar system. The ends of the moving contact wires may be kinked to engage the fixed contact or the latter may have a V-shaped contact block. In another arrangement (Fig. 6), again having four contact pairs per cross-point, the row and column commoning strips are on opposite faces of the same board 50. So-called columns of fixed contacts 59 upon the upper side of the board connect through the board with their commoning strips 53, 55 upon the underside. So-called rows of moving contacts, not shown here, are supported by horizontal cross-members which overly the row commoning strips 56 mounted upon the upper side; the moving contacts are connected to their respective strip at the tags 57. Each row commoning strip 56 is connected through the board to one conductor 52, 54 mounted upon the underside alongside the column commoning strips 53, 55, thereby enabling outside connection to the whole matrix switch to be made along one edge of the board.

Title: Improvements in the manufacture of textile materials
IPC: D01F2/28
Filed: 1930-03-31
Abstract: To give ample warning of the safe ironing temperature, yarn, fabrics, &c. composed of or containing organic derivatives of cellulose have incorporated therewith an organic substance, other than an animal or vegetable oil, which causes scorching at a temperature below that at which the cellulose derivative begins to melt.  Suitable substances include fatty acids, e.g. oleic and p  stearic acids, and their sodium and potassium salts; sodium potassium and aluminium acetates; waxes, e.g. spermaceti and beeswax; proteins, e.g. albumen and gelatins.  Waxes &c. are incorporated in the spinning solution but soluble substances such as sodium acetate are applied to the yarn and fixed therein by a coagulent such as egg albumin.  The substance may be applied in liquid or paste form and penetration may be facilitated by treating the material with swelling agents, e.g. sodium, potassium and ammonium thiocyanates and formic acid.  Derivatives of cellulose include ethyl, methyl and benzyl cellulose and cellulose acetate, formate, propionate, butyrate, and benzoate.  Materials consisting of or containing cellulose esters are advantageously saponified superficially e.g. as in Specifications 304,596, 309,377, and 318,468, [all in Class 2 (ii), Cellulose &c.], but the substance to be incorporated should not be adversely affected by the saponifying treatment.  In an example cellulose acetate is superficially saponified according to the processes of Specifications 304,596 and 309,377 the bath containing ,05 per cent of caustic soda and saponification being continued until the material has suffered a loss of 6 per cent in weight; the material is then treated for 10 minutes in a bath containing 1,5 per cent of sodium acetate and 1 per cent of egg albumen at a temperature of 60 DEG  C., and after removal from the bath is dried on a tenter at 78 DEG -85 DEG  C.

IPC: C22F1/00
Filed: 1969-02-26
Abstract: 1282883 Heat-treating alloys F E WANG 26 Feb 1969 [26 Feb 1968] 10382/69 Heading C7A Certain alloys of the CsCl type are heated above their martensite temperature, cooled at such a rate that martensitic transformation occurs, to a temperature outside the range within which temperature variations cause progressive changes in the electrical resistivity or temperature curve of the alloy, and stored at such a temperature. In a modification the alloy is subjected, within its martensitic transition temperature range, to stress insufficient to cause plastic deformation, when it may be stored inside the above mentioned range. As a further step to the cooling the alloy may be thermally cycled within the defined range until the alloy exhibits a maximum resistivity value. The temperature range may be determined by measuring the resistivity of the alloy while heating to 650-700‹C. and again while cooling, the temperature range being that over which the resistivity values differ between heating and cooling. The alloys concerned are those of Ti-Ni containing 50 to 64% by weight of nickel, and the Ti-Co, Ti-Fe, Zr-Pd, Zr-Rh, Zr-Ru, Hf-Pt, Hf-Ir, and Hf-Os analogues of such alloys; also ternary alloys of formula JL x  M 1-x  where J is a metal of Group IVa of the Periodic Table and constituted atom % of the composition, while L and M are two metals of Group VIII and the same period as metal J, x being greater than 0 and less than 1.

Filed: 1957-03-29
Abstract: 808,550. Electric indicating systems. GENERAL MILLS Inc. March 29, 1957 [April 2, 1956], No. 10406/57. Class 40 (1). A device for keeping the current in a line constant comprises a container 12 (Fig. 1) having a low coefficient of thermal expansion with an hermetically sealed bellows cap 14, filled with mercury 22 with electrodes 16, 18 at the ends, the container also housing a rod 20 of material having a high thermal expansion coefficient, e.g. soft glass, or crystal-line magnesium oxide, whereby an undesired increase in current through the mercury produces an increase in temperature which causes the rod 20 to expand and reduce the crosssectional area of the mercury, thereby increasing its resistance and reducing the current flow to its normal value. The rod 20 may alternatively be a flexible cylinder containing a gas with a high temperature coefficient. By reversing the materials of the container 12 and the rod or cylinder 20 the device becomes a constant voltage regulator. The apparatus is normally enclosed in an evacuated heat shield 24, but may be used as a temperature-resistance transducer, when the heat shield is omitted. The mercury may be replaced by other conductive liquids, e.g. cuprous sulphate solution when used at low voltages, or liquid gallium when used at high temperatures.

Abstract: 178,319. Petersen, W. H., and Allmõnna Svenska Elektriska Aktiebolaget. April 13, 1921. Induction relays.-Relates to induction timelimit relays in which the time for operation varies inversely with the operating-current and consists in arranging for the operating-device to move freely until the desired current value is attained, after which it is carried into engagement with and drives the releasing-mechanism. In the modification shown, the disc a, mounted in the rocking frame b, is normally rotated from the electromagnet f but, on the limit value of current being reached, it is, in addition, lifted bodily upwards by the magnetic forces acting on it so that a worm h on its shaft p comes into engagement with the toothed sector i. which is then driven counter-clockwise to close the contacts k, l. A braking-magnet g and counterweight n facilitate this action, which is carried out against the pull of a spring e. The apparatus may be set for different time limits by varying the initial position of the sector i, and for different current values by varying the number of turns made use of in the operating-coil o.
